Ikertivaq , also known as Ikersuaq or Ikerssuaq , is a bay or fjord in Sermersooq municipality, southeastern Greenland . Tundra climate prevails in the area of the fjord, the average annual temperature in the area being -8 °C . The warmest month is July when the average temperature rises to 0 °C and the coldest is January with -14 °C.
5-404: This fjord has been labeled as one of the most dangerous fjords in the area because of the abundance of pack ice . Large ice floes encumber its entrance, blocking the fjord and keeping the calf ice inside. Ikersuaq extends in a roughly northwest–southeast direction for about 20 km. It is divided into a number of inlets or fjord branches with large active glaciers at their heads. To the south
10-1052: Is "fastened" to a fixed object, drift ice is carried along by winds and sea currents , hence its name. When drift ice is driven together into a large single mass (>70% coverage), it is called pack ice . Wind and currents can pile up that ice to form ridges up to dozens of metres in thickness. These represent a challenge for icebreakers and offshore structures operating in cold oceans and seas. Drift ice consists of ice floes , individual pieces of sea ice 20 metres (66 ft) or more across. Floes are classified according to size: small – 20 metres (66 ft) to 100 metres (330 ft); medium – 100 metres (330 ft) to 500 metres (1,600 ft); big – 500 metres (1,600 ft) to 2,000 metres (6,600 ft); vast – 2 kilometres (1.2 mi) to 10 kilometres (6.2 mi); and giant – more than 10 kilometres (6.2 mi). Drift ice affects: Drift ice can exert tremendous forces when rammed against structures, and can shear off rudders and propellers from ships and strong structures anchored to
15-518: The Southern Ocean . Polar packs significantly change their size during seasonal changes of the year. Because of vast amounts of water added to or removed from the oceans and atmosphere , the behavior of polar ice packs has a significant impact on global changes in climate . Seasonal ice drift in the Sea of Okhotsk by the northern coast of Hokkaidō , Japan , has become a tourist attraction, and
20-506: The bay opens into the North Atlantic Ocean between Dannebrog and Suunikajik islands. The fjord has been described also as a sound . This Greenland location article is a stub . You can help Misplaced Pages by expanding it . Pack ice Drift ice , also called brash ice , is sea ice that is not attached to the shoreline or any other fixed object (shoals, grounded icebergs, etc.). Unlike fast ice , which
25-748: The shore, such as piers. These structures must be retractable or removable to avoid damage. Similarly, ships can get stuck between drift ice floes. The two major ice packs are the Arctic ice pack and the Antarctic ice pack . The most important areas of pack ice are the polar ice packs formed from seawater in the Earth's polar regions : the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of
